I bought this past weekend a '99 LC. Having previously driver a '90 4Runner and a '94 4Runner, and have had a '95 Tacoma driven by a family member, I am very familiar with those vehicles. But the navigation system in the '01 Cruiser is new to me as I hadn't previously paid attention to the trends in the build of the model. What has been the general consensus on this new techno gadget? And could a new unit be purchased (where?) and installed in a '99 LC? What would be the wiring experience needed for such a retrofit?
